SANITARY T.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed ctober'1'7, 1904- Serial No. 228,789.

| To all whom it may concern:

Beit known that I, JOHN L. FRUIN, a citizen of the United States, and a resident of Brooklyn-borough, New York city, and State of New York, have invented certain new and useful Im rovements in Sanitary Ts, of which the fbllowing is a specification.

M invention relates to that type of plumbers 'tting which is known as a sanitary T,

being a fitting intended to form an integral Y part of alwaste-pipe and provided with an openinggzhrough its side by which water or other matter to be carried away by the waste-pipe can be received and with another op9ning'whereby said T may be vented independently of such venting as would naturally arise from its being a part of the main waste-pi e, which of course serves as a vent, provide the part above said T is not at the 2 same time acting as a waste-pipe for something above it.

There are objections, as I have found, to

-. having the waste-opening in the direct line opening, so that .the venting of the main pipe both as to the discharge function and as to the vent function; and one object of my invention is so to construct the T as to have this wastmopening substantially or wholly offset from the direct line of the main waste-pipe, being in the lateral enlargement of the-T, so that whatever is received through said opening flows first down the incline of the enlargement instead of falldirectly into the waste-pipe. By this construction I am able to have the discharge enter the T immediately under the ventis instantaneous and uninterrupted, and al danger of interruption by a discharge coming down the waste-pipe from ahi her level is avoided.

Anotherobject o my invention is so to construct the T that it has a lateral horizontal branch intended to lie wholly within the wall of the room and to receivewhat may be called auxiliary waste and transmit it to the main waste-pipe by causing it to pass direotl under the vent-opening, whereby said auxi 'ary waste is also directly vented without the aid of themain waste-pipe. The main waste-o ening is ordinarily intended auxili waste is intended for washbasins,

bath-tn s,or

for such'artic es as water-closets, while the- My invention, therefore, consists in a sanied to form a length of a main waste-pipe, a lateralenlargement provided with a suitable vent-passage, a main waste branch opening into said enlargement and adapted to project within the interior of the room and discharging immediately under said vent-passage and out of line with the main waste, and an auxiliary vent-passage adapted to lie wholly within the wall and entering said enlargement between the main waste and the ventpassage, whereby the discharge from said auxiliary waste is caused to pass under said vent-passage in entering the main waste.

In the accompany'in drawings I have shown three slightly-di 'erent forms of my improved sanitary T.

In Figure 1 the main waste is set some what lower than in Fig. 2, while in Fig. 3 the auxiliary waste is shown as a two-inch angleinlet instead of a straight-inlet, as shown in Fi 2.

ame letters indicate similar different drawings.

A is the straight portion of the T. B is the vent-passage. C is the main waste. D is the auxiliary waste.

From the description already given the operation of this T will," I think, be readily understood without further explanation.

I claim A sanitary T composed of a straight portion, adapted to form a length of a main waste-pipe, a lateral enlargcment'provided with a suitable vent-passage, a main waste branch opening into said enlargement and adapted to project within the interior of the room and discharging immediately under said vent-passage and out of line with the main waste, and an auxiliary waste-passage adapted to lie wholly within the wall and entering said enlargement between the main waste and the vent-passage whereby the discharge from said auxiliary waste is caused to pass under said vent-passage in entering the main waste.
